This diagnostic and treatment manual is designed for use by medical professionals involved in curative care at the dispensary and hospital levels. We have tried to respond in the simplest and most practical way possible to the questions and problems faced by field medical staff, using the accumulate...d field experience of Médecins Sans Frontières, the recommendations of reference organizations such as the World Health Organization (WHO) and specialized works in each field.

This document sets out the criteria and procedures to be followed by countries in verifying the interruption of yaws transmission. It is intended for use by international verification teams, national yaws eradication programmes and WHO technical staff involved in the eradication of yaws.
This document describes the key areas that national governments should consider for the introduction and scale-up of point-of-care (POC) diagnostics within national programmes, as new innovative POC technologies are being introduced into the market. The next steps taken to include these new innovati...ons within the broader context of national diagnostic networks of conventional laboratories could influence the achievement of the 2030 Fast Track targets for ending the AIDS epidemic.
POC diagnostics, when strategically introduced and integrated into national diagnostic networks, may help catalyse changes that improve the way diagnostics and clinical services are delivered. This document distils this understanding based on programmatic and market experiences of introducing POC diagnostics through catalytic investments in POC HIV technologies across numerous countries in sub-Saharan Africa.

Expert opinion of the European Tuberculosis Laboratory Initiative core group members for the WHO European Region.
Interium guidance, 25 June 2021Timely and accurate diagnostic testing is an essential tool in preventing and controlling the spread of COVID-19. This document describes recommendations for national testing strategies and the use of PCR and rapid antigen tests in different transmission scenarios of t...he COVID-19 outbreak, including how testing might be rationalized in low resource settings. All testing should be followed by a strong public health response including isolating those who test positive and providing them care, contact tracing and quarantine of contacts.

The speed of developing diagnostics for SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), has been quite remarkable. Diagnostics have focused on nucleic acid amplification testing (NAAT) to identify infected individuals in acute-phase disease for timely implementation of mitiga...tion strategies and case management. More and more immunodiagnostics, mostly rapid diagnostic tests, are being made available as an alternative to NAATs. This type of test can be used out-of-laboratory conditions at large scale.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

The internationally recognized criteria for diagnosis of neurocysticercosis include a requirement for neuroimaging techniques, such as computerized tomography (CT) and/or magnetic resonance imaging (MRI), ideally supported by serology. These facilities are not available in all settings, especially i...n rural areas of low-income countries, making it difficult to identify and treat patients. Additionally, there is controversy about the role, type and duration of anthelmintic, antiinflammatory and antiepileptic drug (AED) treatments for different forms of neurocysticercosis.
These guidelines were developed to assist health-care providers in appropriate, evidence-based management of parenchymal neurocysticercosis. The guidelines do not address other forms of neurocysticercosis and do not include management of extraparenchymal disease (including cysticerci in the cerebral ventricles or subarachnoid space). The aim of the guidance is to improve decision-making to ensure appropriate patient care and to avoid misdiagnoses and inappropriate treatment of patients with neurocysticercosis.

9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Leishmaniasis is a complex vector-borne disease involving in its transmission several species of protozoan parasites called Leishmania, a wide variety of animal reservoirs and phlebotomine sandflies vectors. Cutaneous Leishmaniasis (CL) is the most common form of the disease, and its clinical manife...stations vary from few papules to multiple ulcers affecting the skin but also the mucous membranes, leaving permanent scars and serious disability. It is a disfiguring and stigmatizing disease that often has a devastating psychosocial and economic impact on the affected resources limited communities.

Most neglected tropical diseases (NTDs) occur in remote areas of low- and middle-income countries, where health systems are often poorly developed. Therefore, these neglected patients generally lack access to quality preventive, diagnostic, and therapeutic care [1]. The difficulty to access NTD-ende...mic areas, challenging logistics, and the lack of skilled human resources in these areas are also major obstacles to conduct clinical research. We had to face these when conducting a good clinical practice/good clinical laboratory practice (GCP/GCLP)-compliant clinical study in eastern Sudan, a well-known endemic area for visceral leishmaniasis and other NTDs. We share here the challenges related to study preparation and implementation of this GCP/GCLP study that investigated the causes of persistent fever in a rural hospital located in Gedaref State in eastern Sudan. We think this type of paper may be of interest for researchers planning to conduct a clinical trial in a resource-limited setting as well as for funders of such research.

Based on categories related to structure, content, language, and illustrations, the present study provides an evaluation of the quality of educational materials on leishmaniasis available to health services in Brazil. The 18 publications evaluated consisted of four handbooks, four guided studies, fo...ur booklets, and six leaflets. Of the total publications assessed, nine were produced by the Brazilian National Health Foundation (FUNASA), five by State and Municipal Health Departments jointly with FUNASA, and one by the Pan-American Health Organization. The evaluations were also performed by three professionals: a physician specialized in leishmaniasis, a parasitologist, and an information/communications expert. The publications failed to specify key items such as target public, objective, and bibliography. The illustrations, especially in the booklets and leaflets, failed to clarify the text, portrayed biased concepts, and omitted credits and scale. According to this study, informative materials on leishmaniasis distributed in Brazil present major limitations which jeopardize the quality of information they contain.
